This error message will appear when the device is not connected to ActiveSync correctly. Make sure you properly connect the device to the PC through ActiveSync before running RUU.

-> ERROR [206] : MEMORY ALLOCATION

-> ERROR [280] : UPDATE ERROR

When you see any of these error messages, close other running programs on the computer and run RUU again.

-> ERROR [208] : FILE OPEN

-> ERROR [210] : FILE READ

These error messages indicate that RUU lacks certain important files and cannot continue with the update. Please get the complete RUU package again.

-> ERROR [212] : FILE CREATE

-> ERROR [214] : FILE WRITE

-> ERROR [222, 224] : DEVICE NOT RESPONDING

These error messages will appear when remote access control has failed. Check the ActiveSync connection and try running RUU again.

-> ERROR [220] : MAIN BATTERY POWER

This error message will appear when the device’s battery power is not sufficient. Although RUU will instruct you to plug in the AC adapter, it still has to make sure that your device has enough power to upgrade the radio. (Even when you plug in the AC adapter, the device is unable to charge the battery when it is upgrading the radio).

-> ERROR [238] : FILE READ

This error message may appear when, for some unknown reason, the ROM image on the phone is corrupt. Download the whole RUU and try again.

-> ERROR [240] : FILE OPEN

When this error message appears, check whether the downloaded image is placed in the directory of RUU. If, for some unknown reason, you find that the ROM image is not located in the RUU folder, you have to download the RUU and retry again.

-> ERROR [242] : INVALID LANGUAGE

-> ERROR [244] : INVALID MODEL ID

-> ERROR [294] : INVALID VENDER ID

-> ERROR [296] : UPGRADE ONLY

One of these error messages will appear when you use the wrong RUU to do the upgrade. RUU will check if the Model ID and Language ID are compatible with the device. Make sure you use the appropriate RUU tool to upgrade.

-> ERROR [246] : DEVICE NOT RESPONDING

This error message indicates that RUU cannot start the update process. Please contact your service provider for assistance.

-> ERROR [248~260] : UPDATE ERROR

This error occurs when there is an “open port error” before upgrading the CE ROM image.

Solution: You can reset the device and run RUU again. If you still encounter an “OPEN PORT ERROR” again, reset your computer and try again.

-> ERROR [262] : UPDATE ERROR

This error occurs during the CE ROM code upgrade process.

Solution: If this happens, you can just soft-reset the device and run RUU again. The update process will then continue.

Note: At this stage, the Wince is destroyed; instead, it is in upgrade mode.

-> ERROR [264, 274] : CONNECTION

-> ERROR [302~318] : UPDATE ERROR

-> ERROR [320~328] : INVALID COMMAND

These errors seldom occur. However, if one of these errors occur, it could not be recovered and the device had to be sent back to the customer service center. In this case, you have to flash a new ROM code.

-> ERROR [300] : INVALID UPDATE TOOL

This error message will appear when you use the incorrect RUU version to upgrade.

-> ERROR [330] : ROM IMAGE ERROR

This error message will appear when you use the incorrect RUU to upgrade and the image file size is larger than the Flash ROM size. In this case, download the correct RUU version to upgrade.
